Our new user-centric APIs and v5.x.x SDKs offer an improved user and data management experience. However, they may not be at 1:1 feature parity with our previous versions yet.
If you are migrating an existing app, we suggest using iOS Phased Rollout capabilities to ensure that there are no unexpected issues or edge cases. Here is the documentation:
If you run into any challenges or have concerns, please contact our support team at support@onesignal.com
In this release, we are making a significant shift from a device-centered model to a user-centered model. A user-centered model allows for more powerful omni-channel integrations within the OneSignal platform.
To facilitate this change, the externalId approach for identifying users is being replaced by the login and logout methods. In addition, the SDK now makes use of namespaces such as User, Notifications, and InAppMessages to better separate code.
The iOS SDK is making the jump from v3 to v5, in order to align across OneSignal’s suite of client SDKs. This guide will walk you through the iOS SDK 5.0.0 changes as a result of this shift.
Under the user-centered model, the concept of a "player" is being replaced with three new concepts: users, subscriptions, and aliases.
A user is a new concept which is meant to represent your end-user. A user has zero or more subscriptions and can be uniquely identified by one or more aliases. In addition to subscriptions, a user can have data tags which allows for user attribution.
A subscription refers to the method in which an end-user can receive various communications sent by OneSignal, including push notifications, SMS, and email. In previous versions of the OneSignal platform, each of these channels was referred to as a “player”. A subscription is in fact identical to the legacy “player” concept. Each subscription has a subscription_id (previously, player_id) to uniquely identify that communication channel.
Aliases are a concept evolved from external user ids which allows the unique identification of a user within a OneSignal application. Aliases are a key-value pair made up of an alias label (the key) and an alias id (the value). The alias label can be thought of as a consistent keyword across all users, while the alias id is a value specific to each user for that particular label. The combined alias label and alias id provide uniqueness to successfully identify a user.
OneSignal uses a built-in alias label called external_id which supports existing use of external user ids. external_id is also used as the identification method when a user identifies themselves to the OneSignal SDK via OneSignal.login. Multiple aliases can be created for each user to allow for your own application's unique identifier as well as identifiers from other integrated applications.
As mentioned above, the iOS SDK is making the jump from v3 to v5, in order to align across OneSignal’s suite of client SDKs.

import OneSignalFramework- Update the version of the OneSignal-XCFramework your application uses to
5.0.0. - The Package Product
OneSignalhas been renamed toOneSignalFramework. - Location functionality has moved to its own Package Product
OneSignalLocation. If you do not explicitly add this product your app you will not have location functionality. If you include location functionality ensure that your app also depends on theCoreLocationframework. - In App Messaging functionality has moved to its own Package Product
OneSignalInAppMessages. If you do not explicitly add this product your app you will not have in app messaging functionality. If you include In App Messaging functionality ensure that your app also depends on theWebKitframework. - See the existing installation instructions.
The OneSignal pod has added additional subspecs for improved modularity. If you would like to exclude Location or In App Messaging functionality from your app you can do so by using subspecs:
pod 'OneSignal/OneSignal', '>= 5.0.0', '< 6.0'
# Remove either of the following if the functionality is unwanted
pod 'OneSignal/OneSignalLocation', '>= 5.0.0', '< 6.0'
pod 'OneSignal/OneSignalInAppMessages', '>= 5.0.0', '< 6.0'
If you would like to include all of OneSignal's functionality you are still able to use the default pod
pod 'OneSignal', '>= 5.0.0', '< 6.0'
- Update the version of the OneSignalXCFramework your application uses to
5.0.0. - Location functionality has moved to its own subspec
OneSignalLocation. If you include location functionality ensure that your app also depends on theCoreLocationframework. - In App Messaging functionality has moved to its own subspec
OneSignalInAppMessages. If you include In App Messaging functionality ensure that your app also depends on theWebKitframework. - See the existing installation instructions.
The SDK has been split into namespaces, and functionality previously in the static OneSignal class has been moved to the appropriate namespace. The namespaces and how to access them in code are as follows:
| Namespace | Access Pattern |
|---|---|
| Debug | OneSignal.Debug |
| InAppMessages | OneSignal.InAppMessages |
| Location | OneSignal.Location |
| LiveActivities | OneSignal.LiveActivities |
| Notifications | OneSignal.Notifications |
| Session | OneSignal.Session |
| User | OneSignal.User |
Initialization of the OneSignal SDK, although similar to previous versions, has changed. The appId is now provided as part of initialization and cannot be changed. Previous versions of the OneSignal SDK had an explicit setAppId function, which is no longer available. A typical initialization now looks similar to below.
Navigate to your AppDelegate file and add the OneSignal initialization code to didFinishLaunchingWithOptions.
Replace the following:
Objective-C
[OneSignal initWithLaunchOptions:launchOptions];
[OneSignal setAppId:@"YOUR_ONESIGNAL_APP_ID"];Swift
OneSignal.initWithLaunchOptions(launchOptions)
OneSignal.setAppId("YOUR_ONESIGNAL_APP_ID")To match the new initialization:
Objective-C
[OneSignal initialize:@"YOUR_ONESIGNAL_APP_ID" withLaunchOptions:launchOptions];Swift
OneSignal.initialize("YOUR_ONESIGNAL_APP_ID", withLaunchOptions: launchOptions)Remove any usages of setLaunchURLsInApp as the method and functionality has been removed.
If your integration is not user-centric, there is no additional startup code required. A device-scoped user (please see definition of “device-scoped user” below in Glossary) is automatically created as part of the push subscription creation, both of which are only accessible from the current device or through the OneSignal dashboard.
If your integration is user-centric, or you want the ability to identify the user beyond the current device, the login method should be called to identify the user:
Objective-C
[OneSignal login:@"USER_EXTERNAL_ID"];Swift
OneSignal.login("USER_EXTERNAL_ID")The login method will associate the device’s push subscription to the user that can be identified via the alias externalId=USER_EXTERNAL_ID. If that user doesn’t already exist, it will be created. If the user does already exist, the user will be updated to own the device’s push subscription. Note that the push subscription for the device will always be transferred to the newly logged in user, as that user is the current owner of that push subscription.
Once (or if) the user is no longer identifiable in your app (i.e. they logged out), the logout method should be called:
Objective-C
[OneSignal logout];Swift
OneSignal.logout()Logging out has the affect of reverting to a device-scoped user, which is the new owner of the device’s push subscription. Note that if the current user is already a device-scoped user at the time logout is called, this will result in a no-op and the SDK will continue using the same device-scoped user. Any state that exists on this device-scoped user will be kept. This also means that calling logout multiple times will have no effect.
In previous versions of the SDK, a “player” could have up to one email address and up to one phone number for SMS. In the user-centered model, a user can own the current device’s Push Subscription along with the ability to have zero or more email subscriptions and zero or more SMS subscriptions. Note: If a new user logs in via the login method, the previous user will no longer longer own that push subscription.
The current device’s push subscription can be retrieved via:
Objective-C
OneSignal.User.pushSubscription.id;
OneSignal.User.pushSubscription.token;
OneSignal.User.pushSubscription.optedIn;Swift
OneSignal.User.pushSubscription.id
OneSignal.User.pushSubscription.token
OneSignal.User.pushSubscription.optedInTo receive push notifications on the device, call the push subscription’s optIn method. If needed, this method will prompt the user for push notifications permission.
Note: For greater control over prompting for push notification permission, you may use the OneSignal.Notifications.requestPermission method detailed below in the API Reference.
Objective-C
[OneSignal.User.pushSubscription optIn];Swift
OneSignal.User.pushSubscription.optIn()If at any point you want the user to stop receiving push notifications on the current device (regardless of system-level permission status), you can use the push subscription to opt out:
Objective-C
[OneSignal.User.pushSubscription optOut];Swift
OneSignal.User.pushSubscription.optOut()To resume receiving of push notifications (driving the native permission prompt if permissions are not available), you can opt back in with the optIn method from above.
Email and/or SMS subscriptions can be added or removed via the following methods. The remove methods will result in a no-op if the specified email or SMS number does not exist on the user within the SDK, and no request will be made.
Objective-C
// Add email subscription
[OneSignal.User addEmail:@"customer@company.com"];
// Remove previously added email subscription
[OneSignal.User removeEmail:@"customer@company.com"];
// Add SMS subscription
[OneSignal.User addSms:@"+15558675309"];
// Remove previously added SMS subscription
[OneSignal.User removeSms:@"+15558675309"];Swift
// Add email subscription
OneSignal.User.addEmail("customer@company.com")
// Remove previously added email subscription
OneSignal.User.removeEmail("customer@company.com")
// Add SMS subscription
OneSignal.User.addSms("+15558675309")
// Remove previously added SMS subscription
OneSignal.User.removeSms("+15558675309")Below is a comprehensive reference to the 5.0.0 OneSignal SDK.
The SDK is still accessible via a OneSignal static class. It provides access to higher level functionality and is a gateway to each subspace of the SDK.
| Swift | Objective-C | Description |
|---|---|---|
OneSignal.initialize("YOUR_ONESIGNAL_APP_ID", withLaunchOptions: launchOptions) |
[OneSignal initialize:@"YOUR_ONESIGNAL_APP_ID" withLaunchOptions:launchOptions] |
Initializes the OneSignal SDK. This should be called during startup of the application. |
OneSignal.login("USER_EXTERNAL_ID") |
[OneSignal login:@"USER_EXTERNAL_ID"] |
Login to OneSignal under the user identified by the [externalId] provided. The act of logging a user into the OneSignal SDK will switch the [user] context to that specific user. - If the [externalId] exists, the user will be retrieved and the context will be set from that user information. If operations have already been performed under a device-scoped user, they will not be applied to the now logged in user (they will be lost). - If the [externalId] does not yet exist, the user will be created and the context set from the current local state. If operations have already been performed under a device-scoped user, those operations will be applied to the newly created user. Push Notifications and In App Messaging Logging in a new user will automatically transfer the push notification and in app messaging subscription from the current user (if there is one) to the newly logged in user. This is because both push notifications and in- app messages are owned by the device. |
OneSignal.logout() |
[OneSignal logout] |
Logout the user previously logged in via [login]. The [user] property now references a new device-scoped user. A device-scoped user has no user identity that can later be retrieved, except through this device as long as the app remains installed and the app data is not cleared. Note that if the current user is already a device-scoped user at the time logout is called, this will result in a no-op and the SDK will continue using the same device-scoped user. Any state that exists on this device-scoped user will be kept. This also means that calling logout multiple times will have no effect. |
OneSignal.setConsentGiven(true) |
[OneSignal setConsentGiven:true] |
Indicates whether privacy consent has been granted. This field is only relevant when the application has opted into data privacy protections. See [setConsentRequired]. |
OneSignal.setConsentRequired(true) |
[OneSignal setConsentRequired:true] |
Determines whether a user must consent to privacy prior to their user data being sent up to OneSignal. This should be set to true prior to the invocation of initialize to ensure compliance. |
Live Activities are a type of interactive push notification. Apple introduced them in October 2022 to enable iOS apps to provide real-time updates to their users that are visible from the lock screen and the dynamic island.
Please refer to OneSignal’s guide on Live Activities, the Live Activities Quickstart tutorial, and the existing SDK reference on Live Activities.
| Swift | Objective-C | Description |
|---|---|---|
OneSignal.LiveActivities.enter("ACTIVITY_ID", withToken: "TOKEN")See below for usage of callbacks enter(activityId: String, withToken token: String, withSuccess successBlock: OSResultSuccessBlock?, withFailure failureBlock: OSFailureBlock? = nil) |
[OneSignal.LiveActivities enter:@"ACTIVITY_ID" withToken:@"TOKEN"]See below for usage of callbacks (void)enter:(NSString *)activityId withToken:(NSString *)token withSuccess:(OSResultSuccessBlock _Nullable)successBlock withFailure:(OSFailureBlock _Nullable)failureBlock |
Entering a Live Activity associates an activityId with a live activity temporary push token on OneSignal's server. The activityId is then used with the OneSignal REST API to update one or multiple Live Activities at one time. |
OneSignal.LiveActivities.exit("ACTIVITY_ID")See below for usage of callbacks exit(activityId: String, withSuccess successBlock: OSResultSuccessBlock?, withFailure failureBlock: OSFailureBlock? = nil) |
[OneSignal.LiveActivities exit:@"ACTIVITY_ID"]See below for usage of callbacks (void)exit:(NSString *)activityId withSuccess:(OSResultSuccessBlock _Nullable)successBlock withFailure:(OSFailureBlock _Nullable)failureBlock |
Exiting a Live activity deletes the association between a customer defined activityId with a Live Activity temporary push token on OneSignal's server. |
Objective-C
// Enter a Live Activity
[OneSignal.LiveActivities enter:@"ACTIVITY_ID" withToken:@"TOKEN" withSuccess:^(NSDictionary *result) {
NSLog(@"enter success with result: %@", result);
} withFailure:^(NSError *error) {
NSLog(@"enter error: %@", error);
}];
// Exit a Live Activity
[OneSignal.LiveActivities exit:@"ACTIVITY_ID" withSuccess:^(NSDictionary *result) {
NSLog(@"exit success with result: %@", result);
} withFailure:^(NSError *error) {
NSLog(@"exit error: %@", error);
// handle failure case
}];
// Success Output Example:
/*
{
success = 1
}
*/Swift
// Enter a Live Activity
OneSignal.LiveActivities.enter("ACTIVITY_ID", withToken: "TOKEN") { result in
print("enter success with result: \(result ?? [:])")
} withFailure: { error in
print("enter error: \(String(describing: error))")
}
// Exit a Live Activity
OneSignal.LiveActivities.exit("ACTIVITY_ID") { result in
print("exit success with result: \(result ?? [:])")
} withFailure: { error in
print("exit error: \(String(describing: error))")
// handle failure case
}
// Success Output Example:
/*
{
success = 1
}

OneSignal.Notifications.addClickListener(myListener)The Location namespace is accessible via OneSignal.Location and provide access to location-scoped functionality. As of v5.1.0, location sharing must be enabled by setting isShared to true.
| Swift | Objective-C | Description |
|---|---|---|
let isShared: Bool = OneSignal.Location.isSharedOneSignal.Location.isShared = true |
BOOL isShared = [OneSignal.Location isShared][OneSignal.Location setShared:true] |
Whether location is currently shared with OneSignal. As of v5.1.0, this is false by default, and you must set to true to enable sharing. |
OneSignal.Location.requestPermission() |
[OneSignal.Location requestPermission] |
Use this method to manually prompt the user for location permissions. This allows for geotagging so you send notifications to users based on location. |
The In App Messages namespace is accessible via OneSignal.InAppMessages and provide access to in app messages-scoped functionality.
| Swift | Objective-C | Description |
|---|---|---|
let paused = OneSignal.InAppMessages.pausedOneSignal.InAppMessages.paused = true |
BOOL paused = [OneSignal.InAppMessages paused][OneSignal.InAppMessages paused:true] |
Whether in-app messaging is currently paused. When set to true, no IAM will be presented to the user regardless of whether they qualify for them. When set to false, any IAMs the user qualifies for will be presented to the user at the appropriate time. |
OneSignal.InAppMessages.addTrigger("KEY", withValue: "VALUE") |
[OneSignal.InAppMessages addTrigger:@"KEY" withValue:@"VALUE"] |
Add a string-value trigger for the current user. Triggers are currently explicitly used to determine whether a specific IAM should be displayed to the user. See Triggers. If the trigger key already exists, it will be replaced with the value provided here. Note that triggers are not persisted to the backend. They only exist on the local device and are applicable to the current user. |
OneSignal.InAppMessages.addTriggers(["KEY_01": "VALUE_01", "KEY_02": "VALUE_02"]) |
[OneSignal.InAppMessages addTriggers:@{@"KEY_01": @"VALUE_01", @"KEY_02": @"VALUE_02"}] |
Add multiple string-value triggers for the current user. Triggers are currently explicitly used to determine whether a specific IAM should be displayed to the user. See Triggers. If any trigger key already exists, it will be replaced with the value provided here. Note that triggers are not persisted to the backend. They only exist on the local device and are applicable to the current user. |
OneSignal.InAppMessages.removeTrigger("KEY") |
[OneSignal.InAppMessages removeTrigger:@"KEY"] |
Remove the trigger with the provided key from the current user. |
OneSignal.InAppMessages.removeTriggers(["KEY_01", "KEY_02"]) |
[OneSignal.InAppMessages removeTriggers:@[@"KEY_01", @"KEY_02"]] |
Remove multiple triggers from the current user. |
OneSignal.InAppMessages.clearTriggers() |
[OneSignal.InAppMessages clearTriggers] |
Clear all triggers from the current user. |
func addLifecycleListener(listener: OSInAppMessageLifecycleListener?)See below for usage |
(void)addLifecycleListener:(NSObject<OSInAppMessageLifecycleListener> *_Nullable)listenerSee below for usage |
Add an in-app message lifecycle listener. Remove with removeLifecycleListener. |
func addClickListener(listener: OSInAppMessageClickListener)See below for usage |
(void)addClickListener:(NSObject<OSNotificationClickListener>*_Nonnull)listenerSee below for usage |
The OSInAppMessageClickListener.onClickInAppMessage method will be fired on the passed-in object whenever an in-app message is clicked on by the user. Call removeClickListener(listener) to remove |
The OSInAppMessageLifecycleListener protocol includes 4 optional methods.
Objective-C
// AppDelegate.h
// Add OSInAppMessageLifecycleListener as an implemented protocol of the class that will handle the In-App Message lifecycle events.

@implementation AppDelegate
- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Add your implementing class as the listener.

}
func onDidDisplay(event: OSInAppMessageDidDisplayEvent) {

}
}Any object implementing the OSInAppMessageClickListener protocol can be added as a listener. You can call removeClickListener to remove any existing listeners.
Objective-C
// Add this method to object implementing the OSInAppMessageClickListener protocol
- (void)onClickInAppMessage:(OSInAppMessageClickEvent * _Nonnull)event {
NSLog(@"onClickInAppMessage event: %@", [event jsonRepresentation]);
NSString *message = [NSString stringWithFormat:@"In App Message Click Occurred: messageId: %@ actionId: %@ url: %@ urlTarget: %@ closingMessage: %i",

event.result.url,
@(event.result.urlTarget),
event.result.closingMessage];
}
// Add your object as a listener
[OneSignal.InAppMessages addClickListener:self];Swift
class MyInAppMessageClickListener : NSObject, OSInAppMessageClickListener {

let closingMessage = result.closingMessage
}
}
// Add your object as a listener
let myListener = MyInAppMessageClickListener()
OneSignal.InAppMessages.addClickListener(myListener)The Debug namespace is accessible via OneSignal.Debug and provide access to debug-scoped functionality.
| Swift | Objective-C | Description |
|---|---|---|
OneSignal.Debug.setLogLevel(.LL_VERBOSE) |
[OneSignal.Debug setLogLevel:ONE_S_LL_VERBOSE] |
Sets the log level the OneSignal SDK should be writing to the Xcode log. |
OneSignal.Debug.setAlertLevel(.LL_NONE) |
[OneSignal.Debug setAlertLevel:ONE_S_LL_NONE] |
Sets the logging level to show as alert dialogs. |
device-scoped user
An anonymous user with no aliases that cannot be retrieved except through the current device or OneSignal dashboard. On app install, the OneSignal SDK is initialized with a device-scoped user. A device-scoped user can be upgraded to an identified user by calling
OneSignal.login("USER_EXTERNAL_ID")to identify the user by the specified external user ID.
- Changing app IDs is not supported.
- Any
Usernamespace calls must be invoked after initialization. Example:OneSignal.User.addTag("tag", "2") - In the SDK, the user state is only refreshed from the server when a new session is started (cold start or backgrounded for over 30 seconds) or when the user is logged in. This is by design.
- Identity Verification
- We will be introducing Identity Verification using JWT in a follow up release
